Sta-Kool 770 Ultra White Elastomeric Roof Coating is a tough, highly flexible, rubberized roof coating. This high-performance, 7-year warranted elastomeric roof coating resists cracking and peeling. The coating also provides a highly protective barrier which reflects the sun’s heat and destructive UV rays. This helps to cool roof surfaces and reduce interior temperatures. This product is an “investment” which can actually pay for itself in savings on cooling costs. Covers approx 50-75 sq. ft. per Gal. depending on porosity of the surface.

Rated 4.6 out of 5 by 48 reviewers.
Rated 5.0 out of 5.0 by Antique Truck Camper rejuvination After reading several positive reviews on RV sites I ordered this product. My 1972 Amerigo camper has a fiberglass roof that was starting to become porous. I followed the directions and applied 2 coats as directed. This coating covers well, is easy to apply, and is a snap to clean up. I am happy to report my camper is dry even after a Nor'easter! December 27, 2014
Rated 5.0 out of 5.0 by Great Stuff When i had the old swamp cooler removed from the roof of my 83 year old house, the foll roof was exposed. Sure enough next rain we had a small leak. I purchased Sta Kool and this 53 year old single mom along with my 45 year old girl friend got up on the roof and applied it this phenomenal stuff. No leak and my daughter's room is much cooler in the hot Phoenix sun. Clean up was not easy - I pretty much threw away what i was wearing, but other than that this stuff is GREAT! It was easy to apply with rollers and paint brushes (we threw those away too). I would recommend this and I plan on doing the guest house next! Thanks Sta Kool! March 26, 2013
Rated 5.0 out of 5.0 by Good product !!! - fast delivery to front door. Sta-Kool works well. - Took longer than expected, did it over few weeks, every couple days, after getting 5gal. bucket, did a section. - Ordered 1 by 1, when bucket empty, I ordered the next... ended up needing 6 buckets for 1100 sq.ft. home & garage roof. - Did it all by myself, worked well, considering I'm 57yrs. 5'2 woman. - Used 9" & 4" rollers, and 3-4"brush along seems. - Wear clothing you can throw out when done! - I live in High Desert north of L.A., average temp in summer is 90-100's, and I can feel the house is degrees cooler, before turning on the cooler. - And I'm sure when the rare rains come here, Sta-Kool will also protect my roof from leaks. - Product works well even on my asphalt shingles and did not warp or curl, as some other manufacturers warn. - I'm glad I did this, think was a good investment ! (just wish I could afford to buy for a 2nd coat.) - Now I'm only home in neighborhood w/white roof.... guess that makes me president, living in white house ;-) July 19, 2013
Rated 5.0 out of 5.0 by Saved me 1000's $ on new asphalt roof on my home.. Instead of paying a roofing company 5000$ to re-roof my home I purchased 20 gallons of this product and put it on with a plastic broom from the dollar store. I now have a one piece roof and no lost shingles in the 50 - 70 mph winds we have been having. My neighbors have many bair spots on there roofs. Excellent product and easy to put on. I'm 71 years old , If I can do it anyone can and free shipping to my door. Thanks for a fine product. August 10, 2014
Rated 5.0 out of 5.0 by This is great stuff I have a flat roof in Arizona. This coating is heavy, viscous, and sets up in a thick film that stretches nicely with the weather. As the other reviewers said, use a disposable roller, disposable brush, and wear disposable clothes. This coating is sticky and will grab everything until it drys. It's heavy though. I mixed it up in the five gallon bucket then poured it into two 2 gallon buckets to split up the weight. Then I carried the five gallon (now only holding a little over a gallon) up and used it first. I just couldn't drag that big ol' five gallon up a ladder when it was full. April 1, 2014
